Every single thing will be affected and radically changed. Currently the game has only one developer, so you shouldn't rely on fast release. Soon will be added animation, remade scripts and screamers. Some texts in video was changed to avoid spoilers of game plot.
Only a small part of contact was demonstrated. Release of game is planned on middle or end of 2014 year.
